Rule 51. Preserving Claimed Error

(a) Exceptions Unnecessary. Exceptions to rulings or orders of the court are unnecessary.

(b) Preserving a Claim of Error. A party may preserve a claim of error by informing the court—when the court ruling or order is made or sought—of the action the party wishes the court to take, or the party’s objection to the court’s action and the grounds for that objection. If a party does not have an opportunity to object to a ruling or order, the absence of an objection does not later prejudice that party. A ruling or order that admits or excludes evidence is governed by Federal Rule of Evidence 103.
